Crochet Abbreviations Used
SC- single crochet
SC INC- single crochet increase (2 SC in each stitch)
INV
DEC- Invisible decrease (put hook through the FRONT LOOP ONLY of two
consecutive stitches [two loops on hook] Yarn over pull through both
loops. [two loops on hook] Yarn over pull through two loops)
Magic Circle– Make a loop, leaving a long tail to work with. Insert hook in center of loop, yarn over and draw up a loop. Yarn over, pull through to make the first chain (this does not count as a stitch!). Continue to crochet over the loop and tail with the number of stitches called for. (If you need 6 SC, then crochet 6 SC inside the ring.) Pull the tail to close the circle.

Always move your stitch marker to the last stitch in the round. This pattern is worked in continuous rounds.

Bikini Top for your Mermaid Corchet Doll

The pattern will be very different depending on what yarn and hook you use as well as stuffing preferences… But I chain to the desired length and add SC or HDC rows to desired length. I did 4. Then sew it up! Then I use a piece of yarn and connect it to the middle front and tie in the back like an actual swim suit top!Now you need to add some hair!
